Application filed October 28, 1918. Serial No. 260,034.

To all whom it may concern:

Be it known that I, Cmrrrs H. DILLON, a citizen of the United States, residing at Milan, in the county of \Vashtenaw and State of Michigan, have invented certain new and usefulImprovements in Motors, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in motors, and has relation more particularly to a device of this general character especially designed and adapted for use in connection with an expansion fluid, such as steam, and it is an object of the invention to provide a novel and improved device of this general character comprising a plurality of cylinders, together with associated pistons and crank shaft, and wherein a mechanism is operable from the crank shaft to control the flow of motive fluid to the cylinders in regular succession when the motor is in operation.

It is also an object of the invention to provide a novel and improved motor of this general character comprising a plurality of cylinders or motor units arranged substantially in parallelism and radiating from an associated crank shaft, and wherein the motive fluid is admitted within the cylinders or units in regular succession through similar heads of the cylinders or units.

An additional object of the invention is to provide a motor of this general character comprising a novel and improved valve mechanism, and wherein the induction port of each of the cylinders has coacting therewith a swinging valve which is normally maintained by gravity inclosed position and which is thrown into open position through the medium of a rotating cam, and wherein said cam is of duplicate construction and capable of axial movement so that the cam may be adjusted to reverse the operation of the motor or be adjusted to a neutral position to maintain the motor inactive.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved motor, whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure l is a view in elevation with portions broken away of a motor constructed in accordance with an embodiment of my in vention, the associated pistons and crank being indicated by dotted lines;

Fig. 2 is an enlarged sectional view taken substantially on the line 22 of Fig. 1;

Fig. 3 is a fragmentary sectional View taken through the upper portion of my improved motor and substantially on the same line as Fig. 2 with the valve and cam in a second position; and

Fig. A is a fragmentary view in top plan of my improved motor with the removable casing omitted and the cam in a neutral position.

As disclosed in the accompanying drawings, C denotes a casing provided with the hangers 1 whereby the same may be suitably supported in desired position. Rotatably supported by the casing is a crank shaft S provided within the casing with the cranks 2, said cranks being successivelyarranged at relative angles of ninety degrees, as is clearly indicated by dotted lines in Fig. 1.

Supported by the casing C is a plurality of cylinders A, A A and A These cylinders are arranged in parallelism and radial of the crank shaft S. Mounted for rec tilinear movement within each of the cylinders is a piston P operatively engaged in a conventional manner with one of the cranks 2 through the medium of a rod 3. M denotes an exhaust manifold common to all of the cylinders and in communication with each of the cylinders through the eduction port 4 produced in a side wall of the cylinder, and immediately above the coacting piston P when said piston is at the limit of its working thrust, as is clearly illustrated in Fig. 2 of the accompanying drawings.

The outer head 5 of each of the cylinders is provided with an induction or admission port 6 arranged substantially at the axial center of the head 5. The port 6 is in communication with a steam chest B commonto all of the cylinders A, A A and A The steam chest B comprises two imposed sections 7 and 8, the section 8 being readily removable so that desired access may be had within the chest as the occasions of practice may require.

The lower or inner section 7 is provided at opposite sides of each of the openings 6 with transversely disposed partitions 9, and between "each pair of partitions 9 is positioned a flat valve plate 10 which normally closes the adjacent induction or admission port 6 and which plate assumes its normal position by gravity. The valve 10 has one marginal portion in contact with a side wall of the section 7 and the chest B, and said marginal portion 11 of the valve 10 is beveled so that said valve 10 may have requisite swinging or rocking movement relative to the coacting port 6. The inner marginal portion of the plate at substantially its longitudinal center is provided with the upstanding arm or post 12 substantially perpendicular to the valve 10, or more particularly the under or working face of said valve.

Disposed through the chest B and longitudinally thereof is a shaft 14 which is supported both for rotary movement and for endwise movement. One end portion of the shaft 14 extends within an outwardly directed guide casing or shell 15 carried by an end 'of the chest B while the opposite end portion of the shaft 14 extends exteriorly of the chest B at the opposite end thereof. Keyed to the extended portion of the shaft 1.4 is a gear wheel 16, and said wheel 16 is comprised in a train of gears driven from the crank shaft S. This train of gears is preferably inclosed within a casing 17 so that said gears may run in oil. The connection between the gear 16 and the shaft 14 is such as to cause the same to rotate in unison but permits an endwise movement of the shaft 14 independently of the gear 16 for a purpose to be hereinafter more particularly referred to.

Coacting with each of the valves 10 or more particularly the arm or post 12 thereof is an operating member 0, which has its central portion 18 cylindrical and of such diameter as to be free of the arm or post 12 when the member 0 is in neutral position. The opposite end portions of the membenO are provided with the reversely arranged duplicate cams 19 and arranged at opposite sides of a radius.

Each of the cams 19 upon proper adjustment or movement of the shaft 14 is adapted to engage the arm or post 12 of the adjacent valve 10 for lifting the valve 10 at the proper moment for the admission of the motive fluid within a cylinder, an'd'to release said valve 10 to permit the same to return to its normal or closed position after "the piston has traveled a partial distance along its working thrust. It is to be noted that the opposed faces 20 of the cams 19 are inclined so that when it is desired to start or reverse the motor 0 will promptly coact.

with the arm or post 12 upon the requisite endwise movement of the shaft 14 the inclined faces 20 will assure the proper action with a latch mechanism 22 coacting with a rack 23 suitably supported by the chest B.

24 denotes a conduit in communication with the chest 13 and leading from a suitable source of fluid supply. It is also to be understood that power may be transmitted from the crank shaft 8 in any manner or for any purpose desired. In operation, the valves 10 of the cylinders A, A A 3 and A are operated in regular succession. By referring to Fig. 1, the piston P within the cylinder A is at the end of its stroke and the valve 10 coacting with said cylinder has been adjusted into open position for the admission of steam. After the cylinder has traveled a partial distance 'on its working thrust and before exhaust, the valve 10 is closed. Such position i indicated by dotted lines in cylinder A The expansion of the steam confined within the cylinder results in the piston completing its stroke so that when the piston has assumed the position as indicated by dotted lines in cylinder A exhaust will occur, and during the working thrusts of the pistons P within the cylinders A and A the piston P within the cylinder A will have been returned to the position indicated by dotted lines. The operation of the pistons P within each of the cylinders is the same as the foregoing, and occurs in regular succession so that the desired rotation of the shaft S for the transmission of power is obtained. 7 1

From the foregoing description, it is thought to lee-obvious that a motor constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and faci'lity with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the preeise arrangement and formation of the several parts herein shown in cariying out my invention in practice except as hereinafter claimed.
